IMPROVEMENT IN HEATERS.

Spceiliraiion forming part of Letters Patent No. 35,632, elated June 17, 1F62.

To all whom it may concern.-

Beit known that I, SAMUEL B. SEXTON, of the city of Baltimore and State of Maryland, have invented a certain new and useful Improvement in Stoves; and Ido hereby declare. the following to be a full and exact description ofthe same, reference being had to the accompanying drawings, making part of this specification, in which- Figure lis a vertical longitudinal section of a stove illustrating my improvements. Fig. 2 is a vertical transverse section ofthe same at fr m. Fig. 3 is a horizont-.1l section ofthe same at .ll .U-

Similar letters of reference indicate corresponding parts in the several figures.

My said invention consists, first, in the use of an air-heating chamber located above the ire-pot between the conducting and radiating chambers or dues, the said air-chamber communicating at front with the interior of the room and at back with a vertical chamber, from which air is conducted to apartments above; second, in the employment of an airheating chamber, located as above stated and open both at front and back, as a means of producinga circulation of air in contact with the top of a covered fuelsupply chamber; third, in a provision to admit of cleaning the elbow of the eXit-lue,as hereinafter described.

To enable others skilled in the art to make and use my invention, I -Will proceed to describe its construction and operation.

A is the fire-place, B the grate, O the ashdrawer, D the discharge-due, and E a covered fuelsupply chamber.

The above parts may be constructed substantially as described in my patent of April 19, 1859, reissued December 3, 1861, and require no particular description here.

F is an open air-chamber extending through from front to back of the stove and dividing the gas-chamber into two parts, G and G. The chamber G connects with the exit-Hue D, and is provided with a damper, H, by which it may be disconnected from the fire-place A.

I J are radiating columns rising from a horizontal flue, K, and communicating with the chambers G and G', respectively.

L is a casing, which may inclose the top,

back, and sides of the stove, forming an airheating chamber, Z, which may communlcate with the external air, the interior of the room,

and with apartments above in customary manner.

fis an aperture in the rear wall of the airchamber F, forming a communication between the latter and the chamber at back.

The doors M M iu front of the chamber F are also perforated, so that the air has free circulation through the chamber in either drection.

N is an aperture covered by a movable cap, which may be taken out to permit the insertion of a hoe or scraper from the front of the stove into the elbow of the flue D, to withdraw soot therefrom, which soot falls through into the furnace and is consumed.

In lirst kindling the lire the damper H is opened permitting the gas to pass directly upward through the chamber G into the exit-liuc D. When the fire has progressed sulieiently, the damper is closed, and the gases then pass through the chamber G', downward through the column J, horizontally through the flue K, upward through the column Land through the chamber G to the exit-flue.

When the stove is used to heat apartments above as well as that in which it is placed, the chamber F affords largely increased airheating surface. While the registers in the rooms above are open,air from the lower room will pass backward through the said chamber and mingle with that liowing upward to rooms above. Then the said registers are closed, the motion of the air dowing through the chamber F will be reversed. In this ease air entering from without at theback of the stove will pass through the aperture f into the chamber F, and will be discharged into the room in a heated state through apertures in the doors.

The exitilue may, ifpreferred,communicate directly with the column I, instead of through the chamber G. This and other slight modiiications may be made without departing from the essential principles of my invention.

The constant circulation of air through the chamber F, in addition to increasing the heating capacity ofthe stove, is of great value in preventing the overheating and burning out of the fuel-supply chamber (when one is used) and of the upper plate of the furnace. For dining-room use the chamber Fis also very valuable for warming plates and other similar purposes. The front and rearapertures ol the said chamber may, ifdcsircd,be furnished with registers; but for general use this will not be necessary.

The stove is represented in the form in which I prefer to make it for diningroom use when it is intended to be used with a case and front to fit the mantel. The invention is, however, equally applicable to stoves in which a fuelsupply chamber is not used, and the air-chamber F may be used with asimple cylinder, or with various other descriptions of stoves.

The fnelsupply chamber, if used, may be constructed of iron, or of brick, soapstone, or any other material preferred.

The stove may be adapted to stand in front of the mantel or out in the room, or in any other location.

1t will be seen that but one elbow is used in the exit-flue, and this admits of being very readily cleaned.

Having thus described my invcntiomwbat I claim therein as new, and desire to secure by Letters Patent, is-

1. The air-heatingchamber F, located above the lire-pot between the chambers G G', communicating in front with the interior of the room and at back With a chamber, Z, from which heated air is conducted to apartments above1 the said parts being arranged to operate in the manner and for the purposes specified.

2. The employment ofthe air-heating chamber F, located as above .set forth and open both t front and back, as a means of producing a free circulation of air in contact with the top of a covered fue1-supply chamber, E, of any suitable construction.

3. The combination of the chamber F, stoppered aperture N, fine D, and covered opening e of the fuel-supply chamber, all arranged in the manner and for the purposes specified.
